Abstract
The behavior of fine particle (dust) clouds in plasmas is analyzed by theory, simulations, and experiments.The investigation is motivated by basic interest in strongly coupled Coulomb-like systems and by on-going experiments by PK-4 on-board the International Space Station (ISS). This apparatus succeeding PK-3 Plus has a different simple geometry and has a possibility to elucidate another fundamental aspects of fine particle systems in plasmas. We give an overview of the results of eoretical and simulation works and our experiments with the apparatus PK-4J which has a structure similar to PK-4.
